suda.co.uk

brian suda has created several XSLT files to extract microformats from HTML. From that the X2V webservice/favelet emerged. The XSLT and favelet extracts hCard and to produces .vcf (vCard) files and hCalendar to produce .ics (iCal) files. Also in the labs is a universal XMDP validator and a site-wide search spider that recognizes 'no-follow', 'license' and other microformats so they can be used in a more semantic way when displaying search results.

other

• rfc2629.xslt now attempts to generate hCard information (RFC2629 is an XML format for authoring RFCs and Internet Drafts, see example document)
• Andy Hume uses the hcard format to mark-up the names and URLs of commentors on his blog.
• JSCalendar parses hCalendar and produces a displayable HTML table/CSS-based calendar.
